PROCEDURE FOR TREATMENT OF PARTS OF MAGNETIC CONDUCTORS OF ELECTRIC JET-THRUSTERS Russian patent published in 2010 - IPC C23C4/10 C23C4/06 C23C4/18 C21D8/12

Abstract RU 2402629 C2

FIELD: metallurgy.

SUBSTANCE: procedure consists in mechanical processing to specified grade of finish, in high temperature annealing and in coating plasma-sputtering. Also preliminary there is sputtered a sub-layer of inter-metallide NiTi, then a layer out of titanium nitride powder TiN producing summary thickness of layers 200-300 mcm. Upon sputtering items are annealed at temperature below Curie peak - 680-720°C during 0.5-1.0 hours.

EFFECT: upgraded erosion resistance, thermal resistance and fracture strength at simultaneous high magnetic properties and optic ratios of sputtered surfaces.
